In one embodiment, a first actuation assembly has a first actuator, an arm rotatable about an axis, and a first shaft. The first deflection actuator and the arm are rotationally coupled by the rotation shaft, and the arm has at least one pulley that is engaged with a puller wire. The second wire actuation assembly has a second actuator and a second shaft having a spool portion. Each actuation assembly has a friction-inducing element that provides friction torque between components of each assembly such that the actuators are self-holding.011 00I (NI (VN
